Ontology and Software Tools for the Formalization of the Visualisation of Cultural Heritage Knowledge Graphs

Abstract

Over the last decade, several projects have been developed to digitise and semanticise cultural heritage data. They have been developed to preserve and maintain this heritage, but also to make it accessible to all types of users and to other sectors such as tourism and education. These developments combine the use of knowledge graphs and interactive visualisation tools with web technologies. Although remarkably interesting projects have been developed, the data visualisation tools in these projects tend to focus on the project context. Consequently, it is difficult to reuse the results of these projects. In addition, there are characteristics of cultural heritage information, such as uncertainty and spatial and temporal granularity, that have not been considered, and how to deal with them has not been described. The same is true for other aspects, such as the relationships between different objects. Considering these problems, this study presents a model that formalises how to visualise this information. The design of an ontology that implements this model, based on other works such as VUMO or VISO, is described. Furthermore, the design and development of a software framework that allows the visualisation of this information through a web application are presented. The evaluation of the application of this framework in projects such as SILKNOW or Arxiu Valencià del Disseny is outlined.

Query Model Framework Design for Conservation History and Endowments Database: A Case Study on the Digitization of the Sumedang Larang Kingdom’s History and Endowments in Indonesia

“…The method entails query modeling data to define the connection between management and data entities, which is anticipated to have an impact on data sustainability. Dataset collection was carried out as an integral part of the study aimed at developing a monitoring system that was expected to affect data sustainability [37]. DAQMP builds a recurring query model from the data of the initial tables carried alongside the specific data specifications tables containing significant data, such as heritage items containing material like gold, silver, nickel, and wood, or land and buildings with in-depth details of the current area as well as its boundaries [38].…”

Technological Tools for the Conservation and Dissemination of Valencian Design Archives

“…In AVD, a set of semantic data visualisation tools is developed by extending the spatiotemporal visualisation ontology (STEVO) ontology [87] and its viewer. These tools link the formal definition of visualising information with the data in a knowledge graph.…”

“…The future of the platform is guaranteed by a design that allows for high scalability and offers high-Figure 10.

On the left represent the two ways of visualising the relationships between the objects, and on the right, the temporal variation of the spatial distribution of the objects.…”

Open Access to Data about Silk Heritage: A Case Study in Digital Information Sustainability

“…This tool, however, is not designed for use in one single project or data domain. Rather, it pursues a more ambitious goal, as shown by its recent evolution into the STEVO framework [57]. It was designed and developed to represent specified data, in a model that defines how to visualize and interact with the data.…”
